C12 Microphone

Undoubtedly one of the greatest microphones ever made, the original AKG C12 is best known for its clarity and smooth presence rise. To reproduce this unique response we use the same single layer mesh, multi-chambered CK12 capsule, original amplifier design, and Haufe T14/1 transformer. Our RS Series power-supply is included to recreate the originals depth and size, resulting in a microphone with present but very smooth highs, a clear and detailed midrange, and the unmistakeable low-end focus of a CK12 capsule.

Handbuilt to order in Switzerland, the BSA C12 is one of the highest quality microphones available today. As with all our products, we highly recommend taking advantage of our 14-day demo policy to experience its performance first-hand.
